Which thereby enhance the efficiency of heat pump assembly and cooling device.
In the particularly advantageous extension design of one kind of the invention, cooling device is designed for cooling compressor.
In other words, pass through the compressor of cooling device chiller-heat pump.Due to compressor cooling and the heat that is discharged herein
It is inputted in heat pump cycle by the heat exchanger in bypass duct again, to further improve the efficiency of heat pump assembly.Due to
Therefore the waste heat that operation compressor generates will not lose completely, but at least partly recycle and input heat pump again and follow
In ring.
Furthermore the advantages of generating is that it is possible to save the cooling cycle of the outside for cooling down compressor or cooling dress
It sets.Thus reduce cost of investment.Furthermore equipment is improved in the compactedness of configuration aspects, because can save for pressure to be discharged
The add ons of the waste heat of contracting machine, such as cooling fin or cooling tower.
Here it is preferred, in particular, that cooling device is designed for the transmission device of cooling compressor.
Cooling device is especially particularly preferably designed as the oil injection type cooling device of transmission device.
The oil for being commonly provided for cooling transmission device is guided from transmission device heat exchanger herein.In other words, heat is handed over
Exchanger design is oil cooler.
A kind of advantageous design scheme according to the invention, bypass duct includes expansion valve, wherein the expansion valve arrangement
Before heat exchanger.
Thus, it is possible to advantageously adjust the pressure of the working fluid in bypass channel in this way, so that realizing in a heat exchanger
The heating or evaporation of the determination of working fluid.In other words, it adjusts in bypass duct by least one expansion valve and is handed in heat
The pressure of working fluid before parallel operation.
In addition, a kind of preferred design scheme according to the invention, can adjust working fluid by jet pump and evaporate
Evaporating pressure in device.
The adjustment of evaporating pressure is realized in the case where thus, it is possible to not have additional expansion valve inside main heat pump cycle.It changes
Yan Zhi, jet pump are set as expansion valve.
In the advantageous extension design of one kind of the invention, heat pump assembly includes working fluid, and the working fluid has
At least one of the group being made of fluoro ketones and/or HF hydrocarbon and/or hydrogen perhaloalkenes substance.
In other words, at least use fluoro ketones and/or HF hydrocarbon and/or hydrogen perhaloalkenes as working fluid.
Thus high temperature heat pump is advantageously generated, the high temperature heat pump realizes, and lays flat in 100 degrees Celsius or more of temperature waters
Out its heat or its heat is provided for heat loss device.In addition, having fluoro ketones and/or HF hydrocarbon and/or hydrogen perhaloalkenes
Working fluid be particularly advantageous for by heat exchanger low temperature level in absorb heat.
Another advantage of the working fluid is its technical operability.The characteristics of working fluid, is
Good environment compatibility and its security feature, such as incombustibility or low-down a possibility that causing greenhouse effects.
Further advantage, feature and details of the invention is obtained by embodiment described below and with reference to the accompanying drawings.Uniquely
Attached drawing here it is shown that the heat pump assembly of design scheme according to the invention schematical connection figure.
Identical appended drawing reference can be arranged in same type, the of equal value or identical element of effect in figure.
It has been schematically depicted in the drawings the heat pump assembly 1 of design scheme according to the invention.
Heat pump assembly 1 has compressor 2, condenser 6, evaporator 8 and jet pump 42.In addition, heat pump assembly includes using
In the subtask circulation 101,102 of advocating peace of working fluid.Main working cycles 101 constitute heat pump cycle, in the heat pump cycle,
